Now that you are aware of some precautions to take in 2020, let’s go over the biggest and worst data breach of 2019.

The Biggest Data Breach and Hack of 2019


In a year full of hundreds of millions of records being either hacked or stored in unsafe manners, one breach and exposure takes the cake. In October of 2019, an unbelievable 4 billion social media profiles were affected when their records were publicly exposed on an Elastic search server that was not secured.

In total, it is believed that around 1.2 billion unique individuals were exposed in this leak. Hundreds of millions of unique emails were exposed, along with countless phone numbers, social media profiles, locations, names and job titles.

The data originated from a data enrichment company called PDL, but they claim they didn’t own the server, simply that they had aggregated the data found in it. It seems as if a customer of theirs simply didn’t secure the server when that should have been done.

Thankfully, this information was found by security researchers and not hackers or data thieves. If they would have gotten their hands on this information, it would have been one of the largest hacks in the history of the planet. Even still, it is a frightening fact that all of that information was just out there publically available behind no protection.

Other Major Hacks and Data Breaches of 2019.

While the size and magnitude of the aforementioned data leak is tough to match, there were several other breaches and hacks that took place in 2019. Some of the largest include:

  • Marriott hotels announced that nearly 400 million people had their records and credit card information accessed by hackers.
  • A single breach in February saw the information of over 600 million accounts go up for sale on the dark web. The sites affected included Dubsmash, Whitepages, Armor games and over 10 others.
  • An April breach saw the Facebook records of 540 million people exposed after being left on a public and unprotected server. Facebook would experience several other breaches during the year, as well.

In conclusion, hacks and data breaches are only getting larger and more prevalent, so be sure to do all that you can to protect yourself and your company.
